Crystallography of Icosahedral Crystals
The crystallography of icosahedral crystals is constructed. The actual three-dimensional crystal is represented by a three-dimensional cut in a regular six-dimensional periodic crystal with symmetry described by a six-dimensional space group, and the positions of atoms correspond to an arrangement of hypersurface segments. The resulting crystal can not in general be viewed as a space-filling ar...
متن کامل2D quasiperiodic plasmonic crystals
Nanophotonic structures with irregular symmetry, such as quasiperiodic plasmonic crystals, have gained an increasing amount of attention, in particular as potential candidates to enhance the absorption of solar cells in an angular insensitive fashion. To examine the photonic bandstructure of such systems that determines their optical properties, it is necessary to measure and model normal and o...
متن کاملQuasiperiodic Crystals - Experimental Evidence
A review of the experimental evidence which rejects the determination of the Icosahedral phase as periodic is presented. The experiments discussed include various diffraction techniques for the study of the long range order as well the methods to determine the local atomic arrangement.
متن کاملIndexing of Electron Diffraction Patterns of Icosahedral and Decagonal Phases
The atomic arrangements of solids fall into two broad categories. First refers to long range translational order giving rise to sharp diffraction patterns. Second relates to an atomic order that displays diffuse halos. Prior to the discovery of Quasiperiodic translational order in rapidly solidified Al-Mn alloys [1], sharp diffraction peaks were considered to be synonymous to possession of peri...
متن کاملTheory of color symmetry for periodic and quasiperiodic crystals
The author presents a theory of color symmetry applicable to the description and classification of periodic as well as quasiperiodic colored crystals. This theory is an extension to multicomponent fields of the Fourier-space approach of Rokhsar, Wright, and Mermin. It is based on the notion of indistinguishability and a generalization of the traditional concepts of color point group and color s...
